The XFS "lock up" issue is concerning -- it's been a very long time since I've seen any showstopping issues with that filesystem. Is anyone aware of what's going on there?
Yeah would be nice to get more information about that.
We run everything on xfs so that is concerning.

Currently using Kafka + ClickHouse for something very similar.

Thanks for the writeup!

How does ClickHouse compare to Redshift? I'm sure CloudFlare doesn't want to use AWS products, but I am curious if anyone's used both.
The technical aspects are explained very well here.
The whole article explains how and why they got there, it is actually very well written!
